• soil or water bodies that contain a high concentration of organic liquids that are, for instance, the product of decay processes and may reduce considerably the surface tension of water. In addition, the plastron is able to withstand external pressure exceeding 0.4 MPa. The air, which is not able to

• escape from the pockets formed by the honeycombs, is compressed but expands again as soon as the pressure is released, reestablishing the plastron [21][22]. The straight pathway does not provide a solution Transfer problems with the biological models. As fascinating as the air-holding hair cover of

• vapor–liquid–solid systems, but exceeds the values predicted by theoretical studies [17][18]. The Collembola Cryptopygus clavatus changes between superhydrophic water repellance with plastron formation upon submersion under winter conditions and active grazing underwater with no visible plastron under

• situation of a flexible surface structure on a rigid substrate has recently also been modelled [26][27]. A result of that work is an understanding that elastocapillary effects can provide additional stability for Cassie-type suspended liquid states involved in, e.g., plastron respiration [27][28][29]. It
